/* Custom Professional Menu Styling for Pars Medicine
 * v3.0.0 - 2026-02-09
 * IMPORTANT: Dropdown show/hide is handled by the module's inline CSS (scoped #moduleId).
 * This file must NOT set display, opacity, visibility, or transform on .dropdown-menu
 * or .mega-menu-dropdown — those are controlled by the module.
